Contact your health care provider about hair loss if any of these apply (MedlinePlus)
- Hair loss in an unusual pattern, or losing hair rapidly or at an early age.[1]
- Pain or itching with the hair loss, or scalp skin under the area that is red, scaly or otherwise abnormal.[1]
- Bald spots on your beard or eyebrows, or areas of infection on your scalp.[1]
- Weight gain or muscle weakness, intolerance to cold, or fatigue.[1]
- Acne, facial hair or an abnormal menstrual cycle, or male-pattern baldness in a woman.[1]
Other causes of shedding to rule out (MedlinePlus)
- Physical or emotional stress can shed one half to three quarters of scalp hair, and you may not notice it for weeks to months afterward.[1]
- Triggers include high fever or severe infection, childbirth, major surgery or illness, sudden blood loss, crash diets low in protein, and some medicines such as retinoids, birth control pills, beta-blockers and NSAIDs.[1]
What FDA's December 2024 review says
- The most common reactions reported are local irritation, redness or discomfort at the injection site.[2]
- Labels of thymosin alpha-1 products sold outside the United States carry warnings or contraindications for children, pregnancy, breastfeeding, autoimmune disease and immunosuppression.[2]
- After stem-cell transplant it could cause or worsen graft-versus-host disease.[2]
Questions for a dermatologist
- What type of hair loss is this, and does it need any tests to confirm?
- Could a recent illness, fever, surgery, stress or diet change explain the timing?
- Could any medicine or supplement on my list be involved?
- Should the redness or lumps at my injection sites be examined?
